JAMES A. BYERS, OF GENTERVILLE, TENNESSEE.

RAILROAD-TIE.

To all whom it may concern:

Be it'known that I, JAMES A. BYERS, a citizen of the United States ofAmerica, residing at Centerville, in the county of Hickman and State ofTennessee, have invented certain new and useful Improvements inRailroad-Ties, of which the following is a full and clear specification,reference being had to the accompanying drawings, in which Figure l is aview partly in side elevation and partly in Vertical longitudinalsection of my improved tie; Fig. 2 is a plan view thereof; Fig. 3 is anend View; and Fig. 4 is a transverse section taken on the line 4 of Fig.1.

This invention has special reference to the railroad-tie covered by myformer Patent 921,081 dated May 11, 1909, the object of the presentinvention being to improve the construction of said tie, as more fullyhereinafter set forth.

In carrying out my invention, I employ two metallic boxes, 1, 1, whichare preferably of cast iron and are to be set in the road-bed at theproper distance apart to support the track rails. These boxes areconstructed with base plates, 2, which extend beyond the sides and endsof the boxes and are provided on their under sides with in wardly andupwardly beveled flanges or ribs. 3, extending around the four edges ofthe base plates and adapted to take into the ground. Extending upwardfrom the corners and from the sides of the base plates to the tops ofthe boxes are braces, 4, for the purpose of reinforcing the boxes andpreventing collapse of the same in the event of breakage of the samefrom any cause. The end walls of the boxes are formed with angularopenings or notches, which receive the ends of connecting bars, 6,preferably formed of wrought or malleable iron or steel. Theseconnecting bars prevent the spreading apart of the boxes and are firmlysecured therein by means of vertically disposed bolts, 7, extendingthrough the base plates and the tops of the boxes and also serving tosecure the rail-clamps, 8, in position on the tops of the boxes toreceive and hold the track rails.

My present improvements consist, as will be observed, in extending thetwo base plates, 2, of the. boxes inwardly to the center of the roadbed, their inner ends coming Specification of Letters Patent.

close together, and in tying the connecting rods, 6, to, and supportingthem upon spacing and supporting blocks, 9, at the inner ends of saidbase extensions. These supporting blocks are supported on the bases andlie between the connecting rods and are bolted rigidly between the rodsand the bases by vertical bolts, 10, which pass through the base plate,the rods and the intermediate blocks, 9. In this way a much more rigidstructure is obtained, thus reducing injurious vibration and unequalsinking and tilting of the opposite ends of the tie to a minimum. Itwill be observed further that the inner pair of corner braces, at, areextended inwardly to the inner ends of the extended base plates. It willbe observed also that the outer rail clamp, 8, is extended upwardly tofit under and support the head portion of the rail, and that the innerrail clamp is made as high or thick as possible and yet have it avoidinterference with the wheel flange.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a metallic railway-tie, a pair of boxes each having an inwardlyextending base portion and each being provided with means for clampingthe rail thereto, a pair of bars connecting the boxes and rigidlyattached thereto, supporting and bracing blocks between the bars at theinner ends of the extended base plates, and means for clamping saidblocks to the bars and to the base plates.

2. In a metallic railway-tie, the combination of a pair of boxes eachhaving a base plate extended inwardly, and each base plate being bracedto the boxes by inwardly extendin corner braces, rigid connecting barslying between said corner braces, spacing and supporting blocks betweensaid braces and said bars and supported by the extended base plates,said blocks lying between said connecting bars, bolts extending throughthe base plates, supporting blocks and the bars, for the purpose setforth.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses this 15th day of Nov. 1909.
